1) Cisco ASA Information
One is Cisco ASA 5505, the other is Cisco ASA 5510. ASA 5505 is local site, ASA 5510 is remote site. ASA 5505 is ASA 8.0(2) and ASDM 6.0(2). ASA 5510 is ASA 7.2(1) and ASDM 5.2(1).
2) Connection between local and remote site via Metro Link (100Mb). Set one Site-To-Site VPN Tunnel for the two ASA firewall, and disabled this VPN connection at present due to one Metro link is available.
3) I want to ask how can I do if this metro is down, the site-to-site VPN tunnel will enable automatically and if this Metro is up again, the Site-to-Site VPN tunnel will down automatically, in the matter of fact, I want to set as Primary and Secondary backup link.
Please everyone can help me, and recommended some tips, thanks.
